3 Claims.

The present invention relates to safety razors, and particularly to cases and handles therefor, and means of interconnecting the handles with the razor.

A purpose of the invention is to utilize the case as a handle for the razor.

A further purpose is to simplify the interconnection of the case with the razor to function as a handle.

A further purpose is to shorten the over-all length by making the razor fit into a slot or recess at the end of the case when functioning as a handle.

A further purpose is to provide a snap-in connection between a snap-in stud or element on the razor and a snap-in socket on the end of the case.

A further purpose is to make the snap-in stud or element engage a slot to hold the razor in the case and engage a snap-in socket to hold the razor on the end of the case when the case functions as a handle.

A further purpose is to provide a cap which fits over the otherwise open end of the case and suitably has a tongue which fits into the gripping slot of the case which engages the stud when the razor is in the case.

Further purposes appear in the specification and in the claims.

In the drawings I have chosen to illustrate one only of the numerous embodiments in which my invention may appear, selecting the form shown from the standpoints of convenience in illustration, satisfactory operation and clear demonstration of the principles involved.

Figure 1 is a perspective of the case of the invention.

Figure 2 is a perspective of the cap employed in the invention.

Figure 3 is a transverse section along the line 33 of Figure 5, showing the razor in the case.

Figure 4 is a section of Figure 3 on the line 44.

Figure 5 is a section of Figure 4 on the line '5-5.

Describing in illustration but not in limitation and referring to the drawings:

In the prior art it has been customary to keep a safety razor in a case used exclusively for that purpose, and to carry a separate handle for the razor in the case. This either necessitated a fairly large case if the razor was placed in the case in assembled relationship, or has necessitated a reassembly of the razor usually by screwing the handle on the head when the razor is to be used.

2 Even where the razor and head are placed in the case in disassembled relationship, the weight of the handle has been appreciable, and the case has been of increased length due to the need for the handle.

The present invention is designed to simplify the construction of razors, reduce the Weight and complexity and reduce the time required. to place the razor in operation.

In accordance with the invention, the case itself functions as a handle. No screwing on or off of a handle is required, it being merely necessary to pull the razor out of the case and sna the razor head on the end of the case which now functions as a handle.

In accordance with the invention, a single stud or male snap-in element holds the head in a snap-in socket in the end of the handle and the head is desirably prevented from turning by engagement of a bar in a slot.

The stud also desirably serves to hold the razor in the case by engagement of the walls of a retaining slot in the case.

The assembled razor is very compact and short, since the slot in the end of the case adjoining the snap-in socket serves to reduce the length, and the snap-in socket extends inwardly into the case at a position at which it will not interfere with the razor.

Considering now the showing in the drawings, our improved case 29 is made of any suitable resilient plastic material, preferably an elastomer and most desirably nylon, although polyethylene, rubber and synthetic rubber may be used. Other resilient materials such as leather and less desirably resilient metal may be used. The case is hollow and has a closed end 2|, an open end 22, sides 23 and 24, and ends 25 and 26. The side 2% is desirably bulged or curved to fit the contour of the razor.

Knurling ribs 2'1 are provided to aid in obtaining a grip at each corner and run longitudinally.

The side 23 has from its open end part only of the way to the closed end a central longitudinal slot 28 preferably terminating about the middle.

The closed end is slotted from across the full width at 30, so that ribs 3| aolng each side protrude beyond the base of the slot. A snap-in socket 32 extends inwardly from the closed end at the base of the slot, the walls of the socket preferably extending in at 33 beyond the end wall at 33 beyond the end wall a position which will not interfere with the razor, thus shortening the over-all construction. The socket is countersunk at 34 to receive a washer at the base of the stud.

The invention may be conveniently employed with any type of razor, but is preferably used with a razor of the character of Pond copending appli cation Serial No. 293,960 for Reciprocating Razor filed June 17, 1952, which has rollers and reciprocates the blade under the driving action of the rollers. We show such a razor 3 havin rollers 35 and provided with a bar or channel 36 extending end to end of the razor. A male snapin element or stud 31' is secured suitably at the middle of the bar 35, and is suitably provided with a washer 38 at the outside and a washer t?) at the inside. The case is desirably internally rabbeted at slot 28 to receive the washer 38 when the razor slides in from the open end 22.

The stud 3? suitably engages the walls of the slot 28 and resiliently pushes them aside, thus serving to hold the razor in the hollow interior of the case.

When the razor is withdrawn from the case the bar 36 suitably extends across through slot 39 at the end of the case, preventing the razor from turning with respect to the case. The snap-in elements or stud 3'? extends into the snap-in socket 32 and engages due to the resilience of the case holding the razor in position on the end of the case, which functions as a handle.

The countersinking at 3 at the end of the socket permits the washer 38 to be received in the countersunk portion. The stud suitably has a bulbous end as well known.

7 When the razor is resting inside the case, the otherwise open end 22 may be closed by cap ii having an end wall 32 and an end plug portion 43 fitting inside the open end 22 and having resilent side wall overlapping portions are and 35 which respectively engage the outsides of side walls 23 and as or the case. A tongue lfi fits into retainer slot 28 and prevents the'cap from moving laterally as does the plug portion 43.

In operation it will be evident that when the razor is to be put away the cap is removed from the end of the case and the razor is slid in, it being immaterial which end goes first. The snapin element or stud 31' engages in the slot 28 and holds the razor in position. It also acts as a out. Once the razor is resting in the case, the cap is slid on from the end, the tongue 45 riding in the slot 28. i

To remove the razor from the case, the cap is pulled off and then using the stud 31 as a grip, the razor is pushed out. The razor is then readily assembled by bringing the stud 31 into the snapin socket 33 and bringing the bar 36 into the end slot 30.

In view of our invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art to obtain all or part of the benefits or" our invention without copying convenient handle for pushing the razor in and the structure shown, and we therefore claim all such insofar as they fall within the reasonable spirit and scope of our claims.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:

1. In a razor, a resilient plastic case having a hollow interior and having a snap-in socket at one end and a longitudinal slot in said end extending transversely to the socket, and a razor having a snap-in element extending out therefrom which in one position cooperates with the snap-in socket and having a bar transversely to the snap-in element which in one position fits in the slot, the razor in one position resting inside the case and in another position in which the bar fits in theslot and the snap-in element engages in the socket, the case serving as a handle for the razor.

2. In a razor, a resilient case having a hollow interior, having a snap-in socket at one end, having a first slot at that end extending transversely to the socketland having a second slot extending along the side part only of the distance to the end having the snap-in socket, and a razor having extending out at an intermediate point between the ends a snap-in element and having a bar ex tending transversely of the snap-in element, the razor in one position resting inside the case and the walls of the second slot engaging the snap-in element, and in another position the bar on the razor engaging in the first slot and a snap-in element engaging in the snap-in socket, the case serving as a handle for the razor.

3. In a razor, a resilient case having a hollow interior, having a first slot extending from one end part only of the way toward the opposite end along one side, having a second slot extending across the opposite end and having a snap-in 1 socket at the opposite end extending transversely to the second slot, a razor having a bar extending from end to end and a snap-in element extending out transversely to the bar intermediate the ends thereof, the razor in one position resting in the 3 case with the snap -in element gripped by the walls of the first slot, and in another position in which the case serves as a handle the bar resting in the second slot and the snap-in element fitting in the snap-in socket, and an end closure which in one position fits over the end of the case remote from the snap-in socket, having an end portion, two side portions which grip the opposite sides of the case and a tongue which fits into the first slot.
